The importance of examining health behaviors, such as physical activity, among Filipino Americans is highlighted by their higher rates of chronic disease. As physical inactivity has been linked to chronic diseases (U.S. Department of Health and Human Services, 1996), this study investigated the physical activity levels of older Filipinas. This first generation study, compared information obtained by physical activity daily diaries (i.e., self-reported activity) versus ambulatory motion and heart rate monitors (i.e., objectively measured activity) among Filipino American women age 50 years and older. The authors hypothesized that the standardized self-reported activity instruments would be more strongly related to the daily dairies than the objective measure of physical activity. A convenience sample of 15 Filipino American women participated in the investigation. Participants completed a paper and pencil diary to record their activities each day for 3 consecutive days. A within-participant t test analysis was conducted to compare the absolute levels of the physical activity 3-day diary versus the activity levels measured by the ambulatory heart rate/motion sensor monitors. This preliminary investigation consistently found that self-reported measures of physical activity correlated well with each other. The results suggest that physical activity interventions should include both self-report and objective measures of activity given the overreporting indicated in this study.
